friction settings between objects

Post by joal91 » 24 Sep 2017, 17:35

good day

I have designed a tray that carries 54 cylinders on a conveyor belt, these move on the tape and when detected by a sensor, the tape stops.
The problem I have is that by stopping the tape with the tray the cylinders have a vibration which causes their reference points to change and the time to be searched by the robot usually vary and does not take them.

How could I improve this detail that I have?

I attached the video link of the problem I'm having. ... 9.wmv?dl=0

Thank you very much

what you are seeing is typical for certain physics engines. You have several possibilities to reduce/remove that effect:
  • Try to increase a bit the inertia and/or mass of the cylinders
  • Switch to a different physics engine
  • you can also try to use some linear/angular damping (this is physics engine dependent)
  • If you want to make sure that the solution works with all physics engines, point 1 above, or following might help: design your cylinder as a cilinder with an embedded cuboid that is coming out on one or both side(s) of the cylinder. Then group both pure shapes. The result is a standing stability of a cuboid, and a rolling behaviour of a cylinder.
